The accompanying drawing represents at A the general structure of acooking-range of ordinary production, the furnace thereof being shown atB and the brick-Work in part at D.

In carrying my improvement int-o practice I create in one end wall ofthe structure or shell A a vertical rectangular orice or door-Way, E, ofa size sufficient to easily receive the water-back, which is shown at F,and which is passed through the orifice and into the furnace. G in theaccompanying drawin g represents a plate or door which covers and hidesthe orifice E, theA pipes or branches of the water-back extendingthrough holes made in said door.
